[0025] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 3As shown, this embodiment provides a clamping device 100 for clamping a component to be clamped. The component to be clamped can be a complete cable with a sheath, or a portion of the cable structure, such as the cable core. It is understood that in other embodiments, the clamping device 100 can also be used to clamp aluminum-clad Invar wire, aluminum alloy wire, aluminum-clad steel wire, or copper-clad Invar wire, etc.

[0027] The clamping device 100 includes a first clamping member 10 and a second clamping member 20. The second clamping member 20 is disposed at intervals on one side of the first clamping member 10. The first clamping member 10 has a first groove 11 on the side near the second clamping member 20, and the second clamping member 20 has a second groove 21 on the side near the first clamping member 10.

[0028] The clamping device 100 also includes a first elastic block 30 and a second elastic block 40. The first elastic block 30 is attached to the wall of the first groove 11 and has a first friction-increasing hole 31. The second elastic block 40 is attached to the wall of the second groove 21 and has a second friction-increasing hole 41. The cable can be clamped between the first elastic block 30 and the second elastic block 40.

[0029] Thus, the clamping device 100 of this application, by providing a first elastic block 30 in the first groove 11 and a second elastic block 40 in the second groove 21, clamps the cable between the first elastic block 30 and the second elastic block 40, thereby avoiding stress concentration at the clamping position of the cable. Furthermore, the first elastic block 30 is provided with a first friction-enhancing hole 31, and the second elastic block 40 is provided with a second friction-enhancing hole 41, to increase the friction between the first elastic block 30 and the second elastic block 40 and the cable when the cable is clamped by the first elastic block 30 and the second elastic block 40, ensuring clamping stability and further dispersing the clamping stress on the cable.

[0030] Please combine Figure 1 In one embodiment, the clamping device 100 further includes an upper mold 50 and a lower mold 60. The upper mold 50 and the lower mold 60 are spaced apart along the second direction Z, and the first clamping member 10 and the second clamping member 20 are located between the upper mold 50 and the lower mold 60.

[0031] The first direction Y, the second direction Z, and the third direction X can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). The description will be based on the example of the first direction Y being the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Z being the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction X being the X-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0032] Along the second direction Z, the first clamping member 10 is detachably connected to the side of the upper mold 50 near the lower mold 60, and the second clamping member 20 is detachably connected to the side of the lower mold 60 near the upper mold 50. Specifically, the first clamping member 10 has a threaded hole in the area outside the first receiving groove, the second clamping member 20 has a threaded hole in the area outside the second receiving groove, and both the upper mold 50 and the lower mold 60 have threaded holes. The first clamping member 10 is then connected to the upper mold 50 and the second clamping member 20 is connected to the lower mold 60 by bolts or other threaded components. Thus, the first clamping member 10 is detachably connected to the upper mold 50, and the second clamping member 20 is detachably connected to the lower mold 60. At least one of the upper mold 50 and the lower mold 60 can move relative to the other, allowing the first elastic block 30 and the second elastic block 40 to clamp the cable, thereby achieving automatic and rapid clamping of the cable. The detachable connection between the first clamping member 10 and the upper mold 50, and the detachable connection between the second clamping member 20 and the lower mold 60, allows for the replacement of the corresponding first clamping member 10 and the second clamping member 20 according to different cables, thereby improving the applicability of the upper mold 50 and the lower mold 60. For example, when clamping cables of different diameters, it is easy to replace the corresponding first clamping member 10 and the second clamping member 20.

[0033] Furthermore, at least one of the upper mold 50 and the lower mold 60 can move relative to the other, so that the first clamping member 10 and the second clamping member 20 clamp the cable. For example, the lower mold 60 is fixed in position, and the upper mold 50 can be driven to move in the second direction Z by a lead screw linear slide or a cylinder linear slide, thereby moving the upper mold 50 closer to or away from the lower mold 60, so that the first clamping member 10 presses the cable onto the second clamping member 20 or releases the cable.

[0034] Please combine Figures 1 to 3 In one embodiment, the first clamping member 10 and the second clamping member 20 are spaced apart along the second direction Z.

[0035] The first clamping member 10 is generally flat, the second clamping member 20 is generally the same shape as the first clamping member 10, and the first clamping member 10 and the second clamping member 20 are generally the same size.

[0036] Along the second direction Z, the second clamping member 20 has a second side surface P2 on the side near the first clamping member 10. The second side surface P2 is planar, and the direction of the normal of the second side surface P2 is parallel to the second direction Z. Along the second direction Z, a second groove 21 is formed by recessing from the second side surface P2 toward the side away from the first clamping member 10. Furthermore, along the first direction Y, the second groove 21 extends through the surface of one side of the second clamping member 20 to the surface of the other side for cable passage. Along the third direction X, the width of the second groove 21 is smaller than the width of the second clamping member 20.

[0037] The cable portion is housed within the second groove 21, and the connection between the groove wall of the second groove 21 and the second side surface P2 is rounded to prevent the sharp structure formed at the connection between the groove wall of the second groove 21 and the second side surface P2 from scratching the area where the cable is housed within the second groove 21.

[0038] Along the second direction Z, the first clamping member 10 has a first side surface P1 on the side near the second clamping member 20. The first side surface P1 is planar, and the direction of the normal of the first side surface P1 is parallel to the second direction Z. Along the second direction Z, a first groove 11 is formed by recessing from the first side surface P1 toward the side away from the second clamping member 20. Furthermore, along the first direction Y, the first groove 11 extends through the surface of one side of the first clamping member 10 to the surface of the other side for cable passage. Along the third direction X, the width of the first groove 11 is smaller than the width of the first clamping member 10.

[0039] The cable portion is housed within the first groove 11, and the connection between the groove wall of the first groove 11 and the first side surface P1 is rounded to prevent the sharp structure formed at the connection between the groove wall of the first groove 11 and the first side surface P1 from scratching the area where the cable is housed within the first groove 11.

[0040] Please combine Figures 2 to 5 In one embodiment, the shapes of the first groove 11 and the second groove 21 are adapted to the shape of the cable.

[0041] In this embodiment, the cable is circular, and correspondingly, the first groove 11 and the second groove 21 are both arc-shaped. The shape of the first elastic block 30 matches the shape of the first groove 11, and the shape of the second elastic block 40 matches the shape of the second groove 21. That is, the shapes of the first elastic block 30 and the second elastic block 40 are the same as the shapes of the first groove 11 and the second groove 21, respectively, both being arc-shaped. Both the first elastic block 30 and the second elastic block 40 are made of hard rubber, polyurethane, or other high-strength wear-resistant composite materials, which can play a buffering role and avoid stress concentration.

[0042] It is understood that in other embodiments, if the cable is elliptical or other shapes, the shapes of the first groove 11 and the second groove 21 are also correspondingly set to elliptical. Accordingly, the shapes of the first elastic block 30 and the second elastic block 40 are also correspondingly set to elliptical.

[0043] In this embodiment, along the second direction Z, one side of the first elastic block 30 is attached to the groove wall of the first groove 11, specifically by means of adhesive bonding or other methods, to fix the first elastic block 30 to the first clamping member 10. Along the second direction Z, the other side of the first elastic block 30 has a first arc surface P3, which is bent to form a first empty groove 32. The cable portion is housed within the first empty groove 32, and the outer peripheral surface of the portion of the cable housed within the first empty groove 32 is attached to the first arc surface P3. Along the first direction Y, the length of the first elastic block 30 is the same as that of the first groove 11, so that all portions of the cable located within the first groove 11 are covered by the first elastic block 30.

[0044] Furthermore, along the second direction Z, the first elastic block 30 is provided with a first friction-enhancing hole 31 on the side away from the first clamping member 10. Along the second direction Z, the first friction-enhancing hole 31 is formed after being recessed from the side of the first arc surface P3 toward the first clamping member 10.

[0045] The number of first friction-enhancing holes 31 is set to be multiple. Along the first direction Y, multiple first friction-enhancing holes 31 are arranged sequentially at intervals so that when the cable is pressed by the first elastic block 30, the friction between the cable and the first elastic block 30 is greater, thus preventing the cable from moving accidentally.

[0046] In this embodiment, along the second direction Z, one side of the second elastic block 40 is attached to the groove wall of the second groove 21, specifically by means of adhesive bonding or other methods, to fix the second elastic block 40 to the second clamping member 20. Along the second direction Z, the other side of the second elastic block 40 has a second arc surface P4, which is bent to form a second hollow groove 42. The cable portion is housed within the second hollow groove 42, and the outer peripheral surface of the portion of the cable housed within the second hollow groove 42 is attached to the second arc surface P4. Along the first direction Y, the length of the second elastic block 40 is the same as that of the second groove 21, so that all portions of the cable located within the second groove 21 are covered by the second elastic block 40.

[0047] Furthermore, along the second direction Z, the second elastic block 40 is provided with a second friction-enhancing hole 41 on the side away from the second clamping member 20. Along the second direction Z, the second friction-enhancing hole 41 is formed after being recessed from the side of the second arc surface P4 toward the second clamping member 20.

[0048] The number of second friction-enhancing holes 41 is set to be multiple. Along the first direction Y, multiple second friction-enhancing holes 41 are arranged sequentially at intervals so that when the cable is pressed by the second elastic block 40, the friction between the cable and the second elastic block 40 is greater, thus preventing the cable from moving accidentally.

[0049] In this embodiment, the dimensions of the first slot 32 and the second slot 42 are matched with the diameter of the cable to ensure that when cables of different diameters are clamped by the first elastic block 30 and the second elastic block 40, both the first elastic block 30 and the second elastic block 40 have a large contact area with the cable, thereby avoiding stress concentration when the cable is clamped, which is not conducive to the detection of elongation after breakage.

[0050] Specifically, the cable diameter is denoted as d. When d < 2.0 mm, the fillet radius R corresponding to the first slot 32 and the second slot 42 is 0.4 mm to 0.6 mm. When 2.0 mm ≤ d ≤ 3.0 mm, the fillet radius R corresponding to the first slot 32 and the second slot 42 is 0.6 mm to 0.8 mm. When 3.0 mm < d ≤ 3.5 mm, the fillet radius R corresponding to the first slot 32 and the second slot 42 is 0.8 mm to 1.0 mm. When d > 3.5 mm, the fillet radius R corresponding to the first slot 32 and the second slot 42 is 1.0 mm to 1.2 mm.

[0051] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
